Physicalism and the Mind

This book addresses a tightly knit cluster of questions in the philosophy of mind. There is the question: Are mental properties identical with physical properties? An affirmative answer would seem to secure the truth of physicalism regarding the mind, i.e., the belief that all mental phenomena obtain solely in virtue of physical phenomena. If the answer is negative, then the question arises: Can this solely in virtue of relation be understood as some kind of dependence short of identity? And answering this requires answering two further questions. Exactly what sort of dependence on the physical does physicalism require, and what is needed for a property or phenomenon to qualify as physical? It is argued that multiple realizability still provides irresistible proof (especially with the possibility of immaterial realizers) that mental properties are not identical with any properties of physics, chemistry, or biology. After refuting various attempts to formulate nonreductive physicalism with the notion of realization, a new definition of physicalism is offered. This definition shows how it could be that the mental depends solely on the physical even if mental properties are not identical with those of the natural sciences. Yet, it is also argued that the sort of psychophysical dependence described is robust enough that if it were to obtain, then in a plausible and robust sense of ‘physical’, mental properties would still qualify as physical properties

Supported open learning for rural development: some experiences from the Open University, UK

Four key elements which have underpined the OU(UK)s success in delivering an integrated system of supported open learning are outlined. These are: high quality, multi-media teaching materials; locally-based tutorial support; first class research and scholarship and highly professional logistics. The argument is put that when designing any contemporary education programme there are advantages in considering the programme as if it were a learning system. To be responsible, designers also need to consider this within a context of global sustainable development which encompasses environmental decision making. Seminar delegates are invited to consider the question: How can distance education and open learning contribute to the emergence of viable and sustainable rural livelihood systems? It is further argued that a valid response to this question involves surfacing the value positions of the major stakeholders as means to establish what is culturally feasible and so as to define what relationships stakeholders wish to conserve in any organisation that is constituted for the Greater Mekong Sub-Region. Evidence from other contexts suggests that any effective rural development strategy needs to be owned by more than one ministry. This presents particular challenges for a multi-national “university” concerned with rural development. International partnerships have a potential role and the OU(UK)’s collaboration models are summarized

Supplementary skills guides for built environment researchers

Deepening specialised knowledge-base and wider skills of researchers in a wider variety of disciplines are prerequisite for developing successful leadership in higher education, the public sector and industry. In response to this repeated calls for enhancing supplementary skills of the built environment researchers, TG53 (Postgraduate Research Training in Building and Construction) initiated steps to develop and nurture understanding of supplementary skills and providing a common frame of reference for use and further discourse and has developed 6 good practice examples highlighting skills for researchers within the built environment. Accordingly, this TG53 publication is in response to the repeated calls for enhancing supplementary skills of the built environment researchers

Passenger Flows in Underground Railway Stations and Platforms, MTI Report 12-43

Urban rail systems are designed to carry large volumes of people into and out of major activity centers. As a result, the stations at these major activity centers are often crowded with boarding and alighting passengers, resulting in passenger inconvenience, delays, and at times danger. This study examines the planning and analysis of station passenger queuing and flows to offer rail transit station designers and transit system operators guidance on how to best accommodate and manage their rail passengers. The objectives of the study are to: 1) Understand the particular infrastructural, operational, behavioral, and spatial factors that affect and may constrain passenger queuing and flows in different types of rail transit stations; 2) Identify, compare, and evaluate practices for efficient, expedient, and safe passenger flows in different types of station environments and during typical (rush hour) and atypical (evacuations, station maintenance/ refurbishment) situations; and 3) Compile short-, medium-, and long-term recommendations for optimizing passenger flows in different station environments

The concept of segmented wind turbine blades : a review

There is a trend to increase the length of wind turbine blades in an effort to reduce the cost of energy (COE). This causes manufacturing and transportation issues, which have given rise to the concept of segmented wind turbine blades. In this concept, multiple segments can be transported separately. While this idea is not new, it has recently gained renewed interest. In this review paper, the concept of wind turbine blade segmentation and related literature is discussed. The motivation for dividing blades into segments is explained, and the cost of energy is considered to obtain requirements for such blades. An overview of possible implementations is provided, considering the split location and orientation, as well as the type of joint to be used. Many implementations draw from experience with similar joints such as the joint at the blade root, hub and root extenders and joints used in rotor tips and glider wings. Adhesive bonds are expected to provide structural and economic efficiency, but in-field assembly poses a big issue. Prototype segmented blades using T-bolt joints, studs and spar bridge concepts have proven successful, as well as aerodynamically-shaped root and hub extenders

Pricing swing options and other electricity derivatives

The deregulation of regional electricity markets has led to more competitive prices but also higher uncertainty in the future electricity price development. Most markets exhibit high volatilities and occasional distinctive price spikes, which results in demand for derivative products which protect the holder against high prices. A good understanding of the stochastic price dynamics is required for the purposes of risk management and pricing derivatives. In this thesis we examine a simple spot price model which is the exponential of the sum of an Ornstein-Uhlenbeck and an independent pure jump process. We derive the moment generating function as well as various approximations to the probability density function of the logarithm of this spot price process at maturity T. With some restrictions on the set of possible martingale measures we show that the risk neutral dynamics remains within the class of considered models and hence we are able to calibrate the model to the observed forward curve and present semi-analytic formulas for premia of path-independent options as well as approximations to call and put options on forward contracts with and without a delivery period. In order to price path-dependent options with multiple exercise rights like swing contracts a grid method is utilised which in turn uses approximations to the conditional density of the spot process. Further contributions of this thesis include a short discussion of interpolation methods to generate a continuous forward curve based on the forward contracts with delivery periods observed in the market, and an investigation into optimal martingale measures in incomplete markets. In particular we present known results of q-optimal martingale measures in the setting of a stochastic volatility model and give a first indication of how to determine the q-optimal measure for q=0 in an exponential Ornstein-Uhlenbeck model consistent with a given forward curve
